First introduced as a download in 2008, Musaic Box is now available free in your browser. This lovely musical game by Alexander Porechnov mingles elements of tetris, sudoku and hidden object scenes into a point-and-click puzzle that's both unique and very entertaining.
At his behest, you go to your grandfather's house only to discover he's nowhere to be found. Explore the room, gathering fragments of sheet music and notes about famous composers. Completing a musical outline opens the "musaic box" for the next aspect of gameplay: click the music player's cylinder to hear the song then use audio, geometric and symbolic clues to put the puzzle pieces together and reconstruct the song. Enjoy mellifluous music when you succeed and also reap the rewards—a useful item, an unlocked chest, or a new room to discover.
Although it's only a scaled-down sample of the download—which you can read more about and order here in JohnB's review—there is still much to behold in this Flash version of the game. It's gorgeously designed, full of melodious instrumentals and challenging puzzles to be as pleasing to the eyes and ears as it is fun to play!
